  • 1"
  • 2-1/2"



PACLOCK’s heavy-duty 600A padlock provides high security; is precision CNC machined in the USA for quality and dependability; and comes standard with a 6-pin bump and pick resistant rekeyable cylinder. The solid body 600A is machined from 6061 aircraft-grade aluminum, anodized in one of ten available colors, resistant to corrosive environments, and ideal for marine applications.

The 600A is available in several keying options and features a non-key retaining brass actuator and dual locking stainless steel ball bearings. With our design, PACLOCK significantly reduces the ability for the lock to be shimmed and pulled. PACLOCK provides a key retaining option to ensure your padlock gets locked.

The 600A comes standard with a 1” hardened stainless steel shackle that is nearly half an inch thick. With PACLOCK’s quick change shackles, you can easily adapt your padlock to any application with just a turn of a wrench. Change the shackle height or type to meet your needs. Take advantage of PACLOCK’s multiple shackle options.
